2.09 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 2.09 carat oval blue sapphire is a precisely proportioned example of natural Ceylon corundum, supplied by The Natural Sapphire Company. The stone measures 7.67 x 6.69 x 4.76 mm, presenting a balanced oval outline that suits a wide range of settings. The cutting style is faceted, executed as a mixed brilliant cut designed to reconcile color saturation with light return, and the surface presents an excellent polish that optimizes facet definition. Clarity is graded as very slightly included when evaluated at eye level, indicating inclusions that are minor and do not materially obstruct transparency. Color intensity is described as intense, and importantly, this sapphire has received no enhancement, maintaining its natural state and the original characteristics conferred by its Ceylon origin.

The mixed brilliant faceting of this sapphire is a deliberate choice to enhance both scintillation and color depth, combining brilliant style facets on the crown with complementary pavilion faceting to achieve controlled light performance. In practice this means the crown facets capture and scatter incident light into a lively pattern of flash and sparkle, while the pavilion geometry returns a steady field of color to the eye. The excellent polish reduces light loss at facet junctions, improving contrast and perceived brightness. The oval proportions, with a modest table and balanced depth, help preserve color saturation without sacrificing light return, so the gem displays an even, vivid body color under a range of lighting conditions.

When compared to more commonly encountered gemstones, the optical character of corundum places it in a distinctive position. Diamond retains the lead in refractive brilliance and fire, owing to a refractive index near 2.417 and higher dispersion, which produces pronounced white light return and colored flashes. Sapphire, with a refractive index near 1.76 to 1.77 and lower dispersion, does not match diamond for sheer brilliance or fire. However the perception of brilliance in this blue sapphire is strongly influenced by its intense color and excellent transparency, which produce a depth and saturation that diamonds cannot provide in blue. Compared with emerald and other beryls, which commonly show more significant inclusions and a more diffuse light transmission, this sapphire offers clearer light return and a more vivid appearance. Against rubies and other corundum varieties, the optical behavior is similar, but the specific hue, tone, and saturation of this Ceylon piece set it apart through a combination of lively scintillation and saturated blue that appears consistent from face up.

Clarity and origin both contribute materially to the gemstone s visual performance. The very slightly included clarity grade at eye level denotes that inclusions are present but small, and that overall transparency remains high, allowing the cut to do its work in channeling light effectively. Ceylon sapphires are often prized for a particular balance of brightness and color that can read as lively and clean even at competitive saturations, and the absence of enhancement confirms that this balance is inherent rather than induced by treatment. The gem exhibits pleochroic character typical of corundum, with subtle shifts between deeper and lighter blue tones as the stone is viewed from different orientations, a quality that adds dynamic interest without detracting from the consistent face up color.

From a practical standpoint this sapphire combines aesthetic strengths with robust wearability. Corundum rates nine on the Mohs scale, making it suitable for everyday jewelry use in rings, pendants, and other settings where hardness and resistance to abrasion are important. The 2.09 carat weight and the dimensions given make it an appropriate centerpiece for a variety of design proportions, while the excellent polish and well executed facet geometry facilitate straightforward setting and finishing by a jeweler. Because it is natural and untreated, and because of its documented Ceylon origin, the gem carries attributes often sought by collectors and connoisseurs who prioritize provenance and natural material quality. The Natural Sapphire Company provides this information as part of a transparent description, allowing a clear assessment of the sapphire s optical qualities, physical properties, and suitability for intended use.
